A rotating rod 8 passes through the middle of the liquid storage barrel 1, and a reinforcement frame 9 is fixed between the surface of the rotating rod 8 and the inner wall of the liquid storage barrel 1. The liquid storage barrel 1 is a cylindrical structure, and is opened at both ends. A liquid inlet pipe 11 is connected to the upper end of one end of the liquid storage chamber 2, and a liquid outlet pipe 26 is connected to the lower end of one end of the liquid storage chamber 2. The rotating rod 8 is arranged horizontally and is fixedly connected to the liquid storage barrel 1 through the reinforcement frame 9 uniformly fixed on its surface. Brackets 27 are arranged on the outer sides of both ends of the liquid storage barrel 1, and a rotating hole 35 is opened on the upper end surface of the bracket 27. The two ends of the rotating rod 8 rotate through the rotating hole 35. The two ends of the rotating rod 8 are fixed with rotating handles 28. The rotating rod 8 can be rotated to drive the liquid storage barrel 1 to rotate, and can rotate forward or reverse, and adjust the height and angle of the leakage pipe 3. A limit plate 39 is fixed on the surface of the rotating rod 8 and located outside the rotating hole 35. The bracket 27 is a rectangular structure and is vertically arranged. The rotating handle 28 is an L-shaped structure. The limit plate 39 is a circular plate structure and is vertically slidably fitted on the outside of the bracket 27. A connecting hole 37 is opened on the surface of the limit plate 39. A rotating groove 36 is opened on the outside of the bracket 27 and located around the outside of the rotating hole 35. A tightening bolt 38 passes through the inside of the connecting hole 37. The inner end of the tightening bolt 38 is inserted into the rotating groove 36. After the rotating rod 8 drives the liquid storage bucket 1 to rotate and adjust to the training angle, the inner end of the tightening bolt 38 tightens the bracket 27, keeping the rotating rod 8 and the liquid storage bucket 1 stably arranged between the two brackets 27 without shaking. The rotating groove 36 is a circular groove structure, and the depth is less than the thickness of the bracket 27. The connecting hole 37 is a threaded hole structure and is aligned with the rotating groove 36. The tightening bolt 38 is horizontally arranged and threadedly connected with the connecting hole 37, and its inner end tightens the bracket 27. An angle dial 40 is arranged outside the bracket 27 and around the outside of the limit plate 39. The angle dial 40 is a circular ring structure with angle values ​​engraved on its surface. The angle of rotation of the liquid storage barrel 1 and the leakage pipe 3 can be known through the angle dial 40.

[0053] like Figure 2 and Figure 3As shown, a liquid storage chamber 2 is provided in the barrel wall of the liquid storage barrel 1, and an electric push rod 10 is installed inside the liquid storage barrel 1, the inner end of the electric push rod 10 is inserted into the liquid storage chamber 2, and a push plate 24 is fixed to the inner end of the electric push rod 10, and the blocking column 12 is made of rubber material, and its outer end is recessed inside the leakage pipe 3, and the push plate 24 is pressed against the inner end surface of the leakage pipe 3 with a first sealing pad 25. The leakage pipe 3 is fixed to the outside of the liquid storage barrel 1, and the electric push rod 10 is perpendicular to the inside of the liquid storage barrel 1, and its inner end is tightly inserted into the inside of the liquid storage chamber 2 and aligned with the leakage pipe 3. The leakage pipe 3 is a round tube structure, and its outer end is flush with the outer surface of the liquid storage barrel 1. The leaking pipe 3 serves as a simulated leakage point on the surface of the leak-plugging training device. Multiple leaking pipes 3 are arranged at different heights and angles on the outer surface of the liquid storage barrel 1. A sealing column 12 tightly inserted into the leaking pipe 3 is fixed to the side of the pushing plate 24. A first sealing gasket 25 tightly pads the end of the leaking pipe 3 is bonded to the side of the pushing plate 24. The pushing plate 24, the sealing column 12 and the first sealing gasket 25 are driven by the electric push rod 10 to open or close the inner end of the leaking pipe 3, and the pushing plate 24 and the sealing column 12 are driven by the electric push rod 10 to open one or more leaking pipes 3, forming one or more leakage points at different heights and angles, so as to train firefighters to perform leak-plugging operations in response to one or more leakage points at different heights and angles on the tank truck.

[0054] External clean water enters the liquid storage chamber 2 from the liquid inlet pipe 11, and the leakage pipe 3, the color developing pipe 16 and the liquid outlet pipe 26 are all in a closed state. Afterwards, the handle 28 is turned to rotate the rotating rod 8 forward or reversely to drive the liquid storage barrel 1 to rotate, and then the leakage pipe 3 is rotated to adjust to different heights and different angles. The tightening bolt 38 fastens the limit plate 39 to the outside of the bracket 27 to keep the rotating rod 8 and the liquid storage barrel 1 stably set, and the angle of rotation of the liquid storage barrel 1 and the leakage pipe 3 can be known through the angle dial 40. When the firefighters are conducting leak plugging training, the electric push rod 10 can be used to drive the push plate 24 and the blocking column 12 to open one or more leakage pipes 3, and one or more leakage points of different heights and angles are formed on the surface of the liquid storage barrel 1, waiting for the firefighters to conduct leak plugging training, so as to train the firefighters to deal with the leak plugging operations of one or more leak points of different heights and angles on the tank truck, improve the intensity and complexity of the tank truck leak plugging training, and improve the firefighters' skills in dealing with tank truck leak plugging.

[0055] A color developing component is arranged inside the liquid holding chamber 2, specifically, a color developing tube 16 is inserted into the liquid holding chamber 2, the color developing tube 16 is staggered with the electric push rod 10, a color developer accommodating chamber 19 is arranged inside the color developing tube 16, the color developing tube 16 is a round tube structure, the outer end of which protrudes from the inner wall of the liquid holding barrel 1, and the inner end of which is a sealing structure, the color developer accommodating chamber 19 is a threaded groove structure, and the color developer accommodating chamber 19 is connected with the liquid holding chamber 2 through a liquid guide hole 17. A liquid guide hole 17 is opened on the surface of the color developing tube 16 and located inside the liquid holding chamber 2, and a plug-in column 18 is threadedly inserted into the outer end of the color developer accommodating chamber 19, the plug-in column 18 is a threaded column structure, and is threadedly matched with the color developer accommodating chamber 19, and a spacing is left between the inner end and the liquid guide hole 17. A holding groove 15 is provided in the middle of the plug-in column 18. The holding groove 15 is a cylindrical structure, and its inner end is connected to the developer accommodating chamber 19. Its length is less than the length of the plug-in column 18. The tube cover 13 is padded with the second sealing gasket 14 and pressed against the outer end surface of the color developing tube 16. The developer is placed in the holding groove 15. The developer can be selected from natural environmentally friendly dyes of different colors, for example, dyes formed by extracting curcumin from ginger juice, dyes formed by extracting cochineal from cochineal, and dyes formed by extracting hematoxylin from hematoxylin, to color the clean water, so as to simulate various liquids transported in tank trucks, and to make the water leaking from the leakage pipe 3 on the surface of the liquid storage barrel 1 more conspicuous and easy to observe, and to improve the environmental protection performance of the leakage, so as to avoid the liquid leaking during the plugging training from harming human skin and polluting the nearby ground and water source. The outer end of the plug-in column 18 is fixed with a tube cover 13, and the side of the tube cover 13 is bonded with a second sealing gasket 14 padded on the port of the color developing tube 16.

[0056] As the rotating rod 8 drives the liquid storage barrel 1 to rotate to adjust the height and angle of the liquid leakage tube 3, the clean water inside the liquid storage chamber 2 can flush the color developing tube 16, and mix with the color developer through the liquid guide hole 17, the color developer accommodating chamber 19 and the storage tank 15, and the clean water and the color developer in the liquid storage chamber 2 are stirred by the inner ends of the multiple electric push rods 10 and the color developing tube 16, so that the color developer is fully mixed with the clean water and the clean water is colored, so as to simulate various liquids transported in the tank truck, and the liquid leakage tube 3 on the surface of the liquid storage barrel 1 can be leaked. The water coming out is more conspicuous and easy to observe, which is helpful for trained firefighters to quickly find the leakage point of the tank truck. It can also detect the airtightness of the liquid chamber 2. Since the liquid chamber 2 is used to hold clean water for a long time for training, it is easy for the surface of the liquid chamber 2 to rust and leak holes other than the leakage tube 3 to appear. Therefore, after filling the liquid chamber 2 with clean water and mixing with the color developer, the leakage tube 3 is closed, and the inner and outer surfaces of the liquid barrel 1 are observed to determine the airtightness of the liquid chamber 2 to avoid the appearance of leak holes other than the leakage tube 3 on the surface of the liquid chamber 2 due to rust and affect the plugging training.

[0057] A collecting box 5 is installed at the lower end of the liquid storage barrel 1. The length of the collecting box 5 is greater than the length of the liquid storage barrel 1, and the width is less than the diameter of the liquid storage barrel 1. A collecting chamber 7 is arranged inside the collecting box 5. An absorption pipe 6 is connected to the lower end of the collecting box 5. A suction pump 33 is installed at the lower end of the absorption pipe 6. A discharge pipe 34 is connected to the side of the suction pump 33. The air and clean water are absorbed from the inside of the collecting chamber 7 through the absorption pipe 6 by the water pump and discharged from the discharge pipe 34. A liquid recovery frame (not shown in the figure) can be arranged at the outer end of the discharge pipe 34 to recover the collected water in the collecting box 5, which can be repeatedly recycled. The two ends of the collection box 5 are fixed with mounting rods 30, and the surface of the bracket 27 and the position below the rotating hole 35 are provided with mounting grooves 29, and the mounting rod 30 slides through the mounting grooves 29. The surface of the mounting rod 30 and the positions on both sides of the mounting grooves 29 are connected with nuts 31. The collection box 5 can be detachably mounted and adjusted up and down by the mounting rods 30 and nuts 31. The mounting rod 30 is a threaded rod structure and is horizontally arranged. The mounting groove 29 is a long strip groove structure with an opening at the lower end. The mounting rod 30 is installed and connected to the bracket 27 through nuts 31. Stabilizing frames 32 are fixed obliquely on both sides of the bracket 27.

[0058] The upper end of the collecting box 5 is provided with a collecting groove 4, and the upper end of the collecting box 5 is provided with an absorption hole 20. The wind flow formed by the suction of the absorption hole 20 will blow on the surface of the liquid storage barrel 1, so that the moisture on the surface of the liquid storage barrel 1 is quickly dried, and the cleaning cotton 23 is quickly dried. The collecting groove 4 is an arc groove structure, and the absorption holes 20 are evenly distributed on the lower end surface of the collecting groove 4. The collecting groove 4 is connected with the collecting chamber 7 through the absorption holes 20. The cleaning cotton 23 is installed at the upper end of the collecting box 5 and located in the middle of the collecting groove 4. The cleaning cotton 23 is a long strip structure, and its length is greater than the length of the liquid storage barrel 1.

The cleaning cotton 23 brushes and cleans the surface of the liquid storage barrel 1, which can clean the dust attached to the surface of the liquid storage barrel 1 and brush the water of the mixed developer attached to the surface of the liquid storage barrel 1.

[0059] During the firefighters' training, the leaking pipe 3 is opened to simulate the leaking point, and the leak plugging training is carried out. The clean water mixed with the developer will soak the surface of the liquid storage barrel 1, causing the surface of the liquid storage barrel 1 to be wet. After the firefighters' leak plugging training is completed, the leaking pipe 3 is closed, and the rotating rod 8 and the liquid storage barrel 1 are continuously rotated, so that the cleaning cotton 23 brushes and cleans the surface of the liquid storage barrel 1, which can clean the dust attached to the surface of the liquid storage barrel 1 and brush the water mixed with the developer attached to the surface of the liquid storage barrel 1. At the same time, the water pump absorbs air and clean water from the inside of the collecting chamber 7 through the absorption pipe 6, and discharges the air and clean water from the discharge chamber 7. The liquid is discharged through the outlet pipe 34, and a liquid recovery frame (not shown in the figure) can be set to receive the collected water in the collection box 5, which can be reused repeatedly. Moreover, the suction force of the suction pump 33 can form an air flow on the surface of the absorption hole 20 inside the collecting groove 4. When the rotating rod 8 and the liquid holding barrel 1 rotate, the air flow formed by the suction of the absorption hole 20 will blow on the surface of the liquid holding barrel 1, so that the moisture on the surface of the liquid holding barrel 1 is quickly dried, and the cleaning cotton 23 is quickly dried, which is beneficial to the long-term safe use of the liquid holding barrel 1 without rust, and it is convenient for the cleaning cotton 23 to repeatedly brush and clean the surface of the liquid holding barrel 1.

[0060] A first plug hole 22 is formed in the middle of the cleaning cotton 23, and second plug holes 41 are formed at both ends of the collecting box 5. A plug rod 21 is slidably passed through the second plug hole 41 and the first plug hole 22. The plug rod 21 and the collecting box 5 can support the lower end of the liquid storage barrel 1 to prevent the middle of the rotating rod 8 from bending due to the excessive weight of the liquid storage barrel 1. Moreover, the plug rod 21 can be detachably installed, which is convenient for disassembly, installation and replacement of the cleaning cotton 23. The second plug hole 41 is located in the middle of both ends of the collecting groove 4, the first plug hole 22 and the second plug hole 41 are aligned, and both ends of the plug rod 21 protrude from the second plug hole 41 and are evenly distributed at the lower end of the liquid storage barrel 1.

[0061] To sum up, in the first aspect, the present invention sets a liquid storage chamber 2 in the inner wall of the liquid storage barrel 1, the rotating rod 8 passes through the inner middle part of the liquid storage barrel 1, and is fixedly connected to the interior of the liquid storage barrel 1 through the reinforcement frame 9, and the two ends of the rotating rod 8 are rotatably installed and connected with the bracket 27 through the rotating hole 35, the limit plate 39 and the tightening bolt 38, and an angle dial 40 is set on the outer side of the limit plate 39.

[0062] Moreover, a plurality of leakage pipes 3 are arranged at different heights and angles on the outer surface of the liquid storage barrel 1, and the electric push rod 10 drives the push plate 24, the blocking column 12 and the first sealing gasket 25 inside the liquid storage chamber 2 to switch the inner end of the leakage pipe 3 between the open and closed states. External clean water enters the liquid storage chamber 2 from the liquid inlet pipe 11, and the leakage pipe 3, the color tube 16 and the liquid outlet pipe 26 are all in a closed state. Afterwards, the rotating rod 8 is rotated by turning the handle 28 to drive the liquid storage barrel 1 to rotate, and then the leakage pipe 3 is rotated to adjust to different heights and angles. The tightening bolt 38 fastens the limit plate 39 to the outside of the bracket 27, keeps the rotating rod 8 and the liquid storage barrel 1 stably set, and the angle of rotation of the liquid storage barrel 1 and the leakage pipe 3 can be known through the angle dial 40.

[0063] When firefighters are conducting leak plugging training, the electric push rod 10 can drive the push plate 24 and the blocking column 12 to open one or more leakage pipes 3, forming one or more leakage points at different heights and angles, so as to train firefighters to perform leak plugging operations in response to one or more leakage points at different heights and angles on the tank truck, increase the intensity and complexity of tank truck leak plugging training, and improve firefighters' skills in dealing with tank truck leak plugging.

[0064] In the second aspect, the present invention sets a color developing component inside the liquid chamber 2, inserts a plug-in column 18 into the color developing tube 16 in the color developing component, holds a color developer in the receiving groove 15 inside the plug-in column 18, and covers the outer end of the color developing tube 16 with a tube cover 13. As the rotating rod 8 drives the liquid storage barrel 1 to rotate to adjust the height and angle of the leakage tube 3, the clean water inside the liquid storage chamber 2 can flush the color developing tube 16, and mix with the color developer through the liquid guide hole 17, the color developer accommodating chamber 19 and the receiving groove 15, and stir the clean water and the color developer in the liquid storage chamber 2 through the inner end of a plurality of electric push rods 10 and the color developing tube 16, so that the color developer is fully mixed with the clean water, and the clean water is colored, so as to simulate various liquids transported in the tank truck. It can also make the water leaking from the leakage tube 3 on the surface of the liquid storage barrel 1 more conspicuous and easy to observe, which is conducive to the trained firefighters to quickly find the leakage point of the tank truck, and can also detect the airtightness of the liquid storage chamber 2.

[0065] Since the liquid chamber 2 contains clean water for a long time for training, it is easy for the surface of the liquid chamber 2 to rust and form leakage holes other than the leakage tube 3. Clean water can be filled into the liquid chamber 2 and mixed with the color developer, and then the leakage tube 3 can be closed. The inner and outer surfaces of the liquid barrel 1 can be observed to determine the airtightness of the liquid chamber 2 to avoid the formation of leakage holes other than the leakage tube 3 due to rust on the surface of the liquid chamber 2.

[0066] In the third aspect, the present invention detachably mounts the collecting box 5 between the two brackets 27 through the mounting rod 30 and the nut 31, so that the collecting box 5 can be adjusted up and down, and the collecting box 5 is located at the lower end of the liquid storage barrel 1, and the cleaning cotton 23 is detachably mounted inside the collecting groove 4 at the top of the collecting box 5 through the plug-in rod 21, and the top of the cleaning cotton 23 abuts against the lower end of the liquid storage barrel 1. The plug-in rod 21 and the collecting box 5 can support the lower end of the liquid storage barrel 1 to prevent the middle part of the rotating rod 8 from bending due to the excessive weight of the liquid storage barrel 1.

[0067] During the training of firefighters, the leakage pipe 3 is opened to simulate the leakage point, and the leakage point plugging training is carried out. The clean water after mixing with the color developer will soak the surface of the liquid bucket 1, causing the surface of the liquid bucket 1 to be wet. After the firefighters' plugging training is completed, the leakage pipe 3 is closed, and the rotating rod 8 and the liquid bucket 1 are continuously rotated, so that the cleaning cotton 23 brushes and cleans the surface of the liquid bucket 1, which can clean up the dust attached to the surface of the liquid bucket 1 and brush the water of the mixed color developer attached to the surface of the liquid bucket 1.

[0068] At the same time, the water pump absorbs air and clean water from the inside of the collection chamber 7 through the absorption pipe 6 and discharges it from the discharge pipe 34. A liquid recovery frame can be set to recover the collected water at the collection box 5, which can be reused repeatedly. In addition, the suction force of the suction pump 33 can form a wind flow on the surface of the absorption hole 20 inside the collection groove 4. During the rotation of the rotating rod 8 and the liquid storage barrel 1, the wind flow formed by the suction of the absorption hole 20 will blow on the surface of the liquid storage barrel 1, so that the moisture on the surface of the liquid storage barrel 1 is quickly dried, and the cleaning cotton 23 is quickly dried, which is conducive to the long-term safe use of the liquid storage barrel 1 without rust, so that the cleaning cotton 23 can repeatedly brush and clean the surface of the liquid storage barrel 1.

[0069] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0070] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, which should also be considered as the protection scope of the present invention.
